Basically I bought a 2500k and am happy. But i still have that lingering doubt in my mind in that 2 years from now the 8 core bulldozer will be laughing at my 4 core's inferiority. What im also perplexed about is bulldozers architecture. It has 4 logical cores and 4 "support" cores if you will. So instead of BD yielding better performance in the future, will its not-so-effective cores begin show their lower performance allowing the 2500k to keep up? Then i got the chance to re-decide as my father got the fx-8120 and isn't happy with it's gaming performance. I'm currently very happy with my 2500k, it can do 5GHz @ 1.48v and can boot at 5.2 so its by no means a bad chip. Its also by no means a golden chip either...

Long story short, down the line will bulldozer's performance be much better or worse in comparison to my 2500k both in gaming/multimedia and general purpose computing? Thanks OCN and please correct me if im mis-informed

Bulldozer (FX-8120) is not good for general purpose computing. Its FPUs are not as quick as Intel's version. Gaming performance is a bit lower than 2500K but multimedia performance is higher than 2500K (sometime even higher than 2600K, depending on what program are you using). Overall general purpose computing is the part where you have to decide, 2500K is simply far superior on this aspect.

Keep in mind that it is very unlikely for AM3+ MB to have PCIe 3.0. To do that without breaking backward compatibility AMD would need a lot faster HyperTransport, which they currently don't. PCIe 3.0 have already shown to be beneficial in SLI/CF setup.

PS: What happened to HyperTransport Consortium? HyperTransport 3.1 was introduced in 2008 and AM3+ is using 3.0 instead.

hmm... i was planning on getting a gtx 460 now, and then a 7870 (or 2) later so i assume pcie 3.0 would be beneficial for me? or at least, good. i never even thought of that as my current mobo has 3 Pci-express 3.0 slots. And i remember reading about the limitations of HT 3.0 and the PCI express/Memory controller.

Gaming is also my #1 concern at this point.

I think its safe to attribute a portion of BD's performance problems with less than stellar multi-threaded coding, especially for 4+ cores.

What are you basing that on? There are plenty of very parallel-able applications out there. What are you classifying as " less than stellar multi-threaded coding"?

It depends on your definition of "future proof".

At this point in time I would suggest that Vishera/Piledriver will be an ~15% improvement over the current FC CPUs. It's hard to say what will happen down the road with game saftware but it appears that they are finally starting to take advantage of multi-core CPUs.

If I were to buy an FX CPU now it would be the 8120 and OC it to 4.6 or so and enjoy. It OCs, scales and runs games plus everything else just fine.

don't buy BD right now, it's not worth it.

There are select multi-threaded workloads that the 8150 wins at, but the converse is true for the 2500k. I don't think there's much of a reason to get an 8150, especially since there's the 8120. Even that's a hard sell when the 2500k can be had for $180 at some joints.
